Automatic stator coil motor winding machine motor speed control method

Automatic winding machine is mainly used for winding telephone, 3c products in the selection of different types of specifications of electromagnetic coils, such as speaker voice coil, cell phone headset voice coil, VCM motor electromagnetic coil and other special materials. Along with the development of China’s economy, the demand for winding machines has become higher and higher. The requirements of the electromagnetic coil winding company for the winding machine are the stability of the use of performance, practical operation convenience, functional perfection, and good appearance.
Electromagnetic coil winding process technology: First, according to the precise positioning tooling fixture, to ensure the coaxiality of the frame and effective operation. In the process of electromagnetic coil winding, the rate starts from zero, and then slowly rises the rate to ensure that the winding spindle can be stable, smooth and chatter-free operation at any rate. In the winding Ф0.018 mm wire wrapped wire, to ensure that it does not stop, winding line neatly, no leakage, no damage to the surface, no pressure stacking, so that it can be considered to meet the standard.

In order to adapt to the processing process of electromagnetic coils, automatic winding machine needs to be configured with spindle speed control function, winding machine equipment should be processed by the type of differences in its configuration also varies, we are more familiar with the type of spindle motor AC motor, DC motor, servo-driven motor these three, some of these motors selected speed control methods have different characteristics.

A, AC motor speed control method: this type of motor itself is no speed control function, it has to be based on electromagnetic speed control equipment or another installed frequency converter to achieve the speed control function, in the winding machine and equipment, we are more common is the frequency converter speed control method, according to the control system of the winding machine and equipment to manipulate the frequency converter so that the motor has the function of speed control, the method also has the corresponding role of energy saving and emission reduction.

Second, the DC motor speed control method: DC motor to supply the power supply into DC power to drive the motor operation, so DC motors are configured with DC speed control board or brushless driver to drive the manipulation of the motor, because the motor size is small in the small winding machine equipment in the application of a larger amount.

Third, the servo-driven motor speed control method: it belongs to the high precision operation components for high precision winding machine and equipment, with a special type of driver selected to achieve closed-loop operation and manipulation, the biggest feature of this type of motor is the constant rotation distance, closed-loop operation, to achieve high precision electromagnetic coil processing process requirements.

Automatic wire winding machine automatic wire row, accurate positioning, process technology manipulation strong. The whole process of traditional type manual wire winding has to be joined by wire winding workers, automatic wire winding machine to achieve flat automatic wire rows, machine and equipment equipped with stepper motors and high precision screw wire row accuracy is much higher than manual wire winding, according to the special control system can reach the electromagnetic coils and insulation paper, the middle tap, both sides of the insulation operation process.

Automatic winding machine tension stability, electromagnetic coil compact. Machine and equipment selection of special flat wire tension controller mechanism, can make the wire coiling process to maintain stability, rather than the destruction of the enameled wire, the appropriate tension is important for the generation of flat wire, automatic winding machine selection can increase the total weight of the electromagnetic coil and quality consistency, so that the electromagnetic coil shape looks good, the overall denseness is high.
